Easily Installed Folded Trampoline

ABSTRACT

This invention refers to a folded trampoline which can be installed easily. It is equipped with tubes aimed at supporting bed surface as well as feet outside the bottom of the tubes. There are folding devices between the tubes and the feet, which consist of exterior folding units, interior folding units, handle, plug pin and reset spring. The exterior folding units which are furnished with locating holes, plus the interior folding units, are connected with tubes, and the feet linked with the inner side of the exterior folding units are articulated with the interior folding units and armed with through-holes which plug pin can go through. This invention has several elastic cords corresponding to fixed units. During installation, one end of the elastic cord will be inserted into the fixed unit, and the other end will go through the ring and the tube successively. After passing through all the rings of elastic cord between two legs, the other end shall be inserted into the fixed unit of the first neighboring elastic cord to assure quick installation.

TECHNICAL FIELD

This invention refers to an easily installed folded trampoline in thetechnical field of trampoline.

TECHNICAL BACKGROUND

Bedjump has become increasingly popular among ordinary families in dailylife as a sport and recreational activity. Today, the trampoline in themarket is made of iron tube, which leads to heavy product and gives riseto rust easily. This product will take up much space when not used, andit is not convenient to install since the jumping sheet is connectedwith only one elastic cord.

CONTENTS OF INVENTION

To address problems above, this invention proposes one folded trampolinewhich can be easily installed and stored.

To achieve the aim above, this invention puts forward a scheme asfollows:

The folded trampoline is equipped with tubes aimed at supporting bedsurface as well as feet outside the bottom of the tubes. There arefolding devices between the tubes and the feet, which consist ofexterior folding units, interior folding units, handles, plug pins andreset springs. The exterior folding units which are furnished withlocating holes, plus the interior folding units, are connected withtubes, and the feet linked with the inner side of the exterior foldingunits are articulated with the interior folding units and armed withthrough-holes which plug pin can go through. The upper part of thehandle is linked with the inner wall of the feet, and the other end isupturned outwards. The plug pin is linked with the upper part of thehandle through locating hole and through-hole.

The two ends of the plug pin differ in diameter and there is a stepsurface between these two ends.

One side of the through-hole near the handle is equipped with springstop.

-   -   There is a reset spring between the step surface of the plug pin        and the spring stop.

The tube is characterized by round shape or polygon.

Beneficial results of this invention are as follows: this invention hasseveral elastic cords corresponding to fixed units. During installation,one end of the elastic cord will be inserted into the fixed unit, andthe other end will go through the ring and the tube successively. Afterpassing through all the rings of elastic cord between two legs, theother end shall be inserted into the fixed unit of the first neighboringelastic cord to assure quick installation.

SPECIFIC IMPLEMENTATION MODE

Description on the specific implementation mode of this invention willbe made in combination with examples for the sake of betterunderstanding of this invention.

EXAMPLE

As shown by FIGS. 1-3, the folded trampoline which can be easilyinstalled is equipped with tubes 1 aimed at supporting bed surface aswell as feet 2 outside the bottom of the tubes 1. There are foldingdevices 3 between the tubes 1 and the feet 2, which consist of exteriorfolding units 3-1, interior folding units 3-2, handles 3-3, plug pins 4and reset springs 7. The exterior folding units 3-1 which are furnishedwith locating holes 6, plus the interior folding units 3-2, areconnected with tubes 1, and the feet 2 linked with the inner side of theexterior folding units 3-1 are articulated with the interior foldingunits 3-2 and armed with through-holes 5 which plug pin 4 can gothrough. The upper part of the handle 3-3 is linked with the inner wallof the feet 2, and the other end is upturned outwards. The plug pin 4 islinked with the upper part of the handle 3-3 through locating hole 6 andthrough-hole 5. The two ends of the plug pin 4 differ in diameter andthere is a step surface 4-1 between these two ends. One side of thethrough-hole 5 near the handle 3-3 is equipped with spring stop 5-1.There is a reset spring 7 between the step surface 4-1 of the plug pin 4and the spring stop 5-1. Every interior folded unit 3-2 is connectedwith fixed unit 9 of the elastic cord.

When this invention is used, the handle 3-3 shall compress the springwith plug pin for the sake of inward compression. The feet can be foldedinwardly as the plug pin 4 moves away from locating hole 6 of theexterior folding unit 3-1. During installation, the plug pin 4 shall bealigned with locating hole 6 and reset by reset spring 7 so that thefeet 2 will stand firmly after plug pin 4 passes through locating hole6. In this invention, the tube characterized by round shape or polygonis easy to use and occupy little space after being folded.

All above are preferential examples of this invention. It is worthnoticing that on the premise of following the principle of thisinvention, ordinary technicians in this technical field are allowed tomake improvements and modifications that shall also fall within theprotective scope of this invention.
